RAILROADHSRAIL CHAIR.

SPECIFICATION forming part of Letters Patent No. 363,167, dated May 1'7, 1887.

Application filed July 20, 1886. Serial No. 209,428. (No model.)

To cZL whom it may concern:

Be it known that I, ISAAC A. PERRY, a citizen of the United States, residing in filmington, Delaware, have-invented certain Improvements in Railroad-Rail Chairs, of which the following is a specification.

The object of my invention is to construct a rail-chair whereby the rails may be firmly retained without the use of bolts and nuts, and' 1o 'without the necessity of forming boltlloles in the rails near the ends.

In the accompanying drawings, Figure l is a perspective view of my improved rail-chair, showing the parts detached from each other;

I5 Fig. 2, a transverse section of the chair; and Fig. 3, a sectional plan view on the line I 2, -Fig. 2.

The chair is composed of opposite clamps,

A A', each comprising abase-plate, c, and side 2o web, b, for embracing the flange of the rail and bearing against the central web of the saine.

On each base-plate are formed projecting tongues el, these tongues having beveled faces ff, so that in tting the two parts of the chair together the tongues will interlock with each other, and as the two parts o f the chair are moved longitudinally in opposite directions the effect of the engagement of the interlock 3o ing beveled tongues will be to draw the two parts of the chair laterally toward. each other, and thus securely clamp and confine the rail or rails between the two parts of the chair.

Each part of the chair has at one end a lug,

g, for receiving the blows of aha1nmer,\vherc by it is driven longitudinally, and in the base of each cha-ir is a recess, h, for the reception of a tapered transverse key, B, which serves to complete the tightening of the two parts of 4o the chair and to prevent the loosening of the same after it has been tightened, a spike-such as shown by dotted lines in Fig. 3-or some other available retainer, being employed to prevent the withdrawal of the key B after it has been driven to its place.

My improved chair may be used as a support for the rail at different points throughout its length, or simply as a means of clamping the ends of adjoining rails together 5 and if 5o it is desired to prevent creeping of the rail or rails in the chair, the opposite clamps may have lugs i for adaptation to recesses formed by removing the corners of the rail-flange at each end ofthe rail, as shown in Fig. 3, or the openings on, for the reception of the spikes, whereby the chair is secured to the cross-tie or other support, may be such, as shown in Fig. 3, as to necessitate the formation of nicks in the flanges of the Vrail for receiving portions of the spikes. When this nieking of the rail- 6o flanges is not considered advisable, however, the openings m may be outside the limits ot' the rail-iiange.

In order to strengthen the base-plate A of each portion of the chair, I secure 'to the un- 55 der side of the same a plate, p, which also serves to prevent vertical displacement of one portion of the chair independently of the other. i

1. The within-described rail-chair, consisting of opposite clamps having base-plates with interlocking beveled tongues and transverse recesses and a transverse tightening and retaining key adapted to said recesses, all sub- 7 5 stantially as speeitied.

2. The within-described rail-chair, consisting of opposite clampingeplates having strikingelugs at the ends and base-plates with interlocking beveled tongues, all substantially 8o as specified.

3. The within-described rail-cl1air, consisting of op poste clamps having base-plates with interlocking beveled tongues and strengthening-plates beneath said baseplates, all snb- A stantially as specified.

4. The within-described rail-chair, consist ing of opposite clamps having longitudinally beveled tongues and lugs engaging wit-h recesses in the rails, the tongues serving by en.- 9o gagement with each other to draw the clamps laterally together and the lugs entering recesses in the rails and serving to prevent longi tudinal movement of said rails in the clamps,- alI substantially as specified. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ISAAC A. PERRY.
